Recently, the social/national necessity for a light emitting diode (LED)is rapidly increased for the eco-friendly purpose/low-carbon purpose andfor the purpose of reducing energy consumption.

In general, to install lighting apparatuses in premises, buildings, andpublic places, the use purpose and the management/control of thelighting apparatus must be planed from a time point at which thebuildings are designed.

The light emitting diode (LED) is a kind of a semiconductor device toconvert electrical energy into light.

The LED has advantages of low power consumption, the semi-permanent lifespan, a rapid response speed, stability, and environmental friendlinesswhen comparing with existing light sources such as fluorescent lamps andlight bulbs.

Accordingly, many studies and researches have been performed tosubstitute the existing light sources with LEDs. The LEDs have beenincreasingly used as light sources of lighting apparatuses such asvarious lamps, liquid crystal displays, electric boards, and streetlamps used indoors or outdoors.

However, even though the LEDs have the efficiency or the above technicaladvantages, the LEDs have practical problems in that the LEDs are highlypriced and have the limitation in the technical differentiation toovercome the price higher than that of an existing lighting apparatus.

DETAILED DESCRIPTION

Hereinafter, the suggested embodiment will be described.

Hereinafter, the embodiments will be described in detail with referenceto accompanying drawings. The technical spirit of the disclosure is notlimited to the embodiments. In addition, any other embodiments that aredeteriorated by addition, change, and deletion of component parts orincluded within the scope of the spirit of the disclosure will be easilyproposed.

In addition, although terms used in the embodiments are selected fromgeneral terms that are currently used, an applicant may arbitrarilysuggest terms in specific cases. Since the terms suggested by theapplicant will be described in detail in relation to operations andmeanings in a corresponding description part of the embodiments, theembodiments should be understood in relation to the operations andmeanings represented in the terms instead of names of the terms.

In the following description, when a predetermined part “includes” apredetermined component, the predetermined part does not exclude othercomponents, but may further include other components if there is aspecific opposite description.

FIG. 2 is a view showing a lighting control system according to thefirst embodiment.

As shown in FIG. 2, the lighting control system according to the firstembodiment includes a movable remote controller 100 and a lightingdevice 200.

The remote controller 100 and the lighting device 200 may makebi-directional communication with each other. The communication schememay include a Bluetooth scheme, which is one of short range wirelesscommunication schemes, but the embodiment is not limited thereto. Thefollowing description will be made by limiting the communication schemebetween the remote controller 100 and the lighting device 200 accordingto the first embodiment to the Bluetooth scheme.

When the remote controller 100 and the lighting apparatus 200 make thebi-directional communication through the Bluetooth, the remotecontroller 100 and the lighting apparatus 200 include wirelesscommunication modules 110 and 240, which will be described later,respectively.

If the remote controller 100 receives an input according to themanipulation of a user, the remote controller 100 transmits a signalaccording to the user input to the lighting apparatus 200 through theBluetooth.

The signal transmitted from the remote controller 100 to the lightingapparatus 200 may include a brightening control signal, a color controlsignal, and an on-off control signal of a light emitting deviceconstituting the lighting device 200.

In this case, the Bluetooth refers to a communication standard to makedata communication by using a frequency band of 2.4 GHz within the shortrange of about 10 m to about 100 m. The communication standard includesprotocols to cope with the interference caused when the same frequencyis used or to identify devices.

The remote controller 100 and the lighting device 200 according to thefirst embodiment follow a Bluetooth low energy (BLE) standard.

When comparing with an existing Bluetooth standard, the BLE standardprovides a less duty cycle, allows low-price production, and allows thepower consumption to be significantly reduced due to a low data rate. Inaddition, the BLE standard has advantages in that the connectionprocedure between devices is simplified, and the package size is reducedwhen comparing with the packet size recommended in the existingBluetooth.

The BLE standard allows the realization of two modes such as a dual-modeand a single-mode. The dual-mode employs a low energy technology sharedwith an existing Bluetooth device, and is mainly applied to a mobileterminal such as a cellular phone. The single-mode is applied to anindividual product such as a sensor and has the same protocol structureas that of the dual-mode.

The BLE standard used in the remote control device 100 according to thedisclosure may be realized at the dual-mode or the single-mode.

The remote control device 100 as described above may include a mobileterminal or a remote controller.

In other words, the remote controller 100 may be a mobile terminal tomake BLE communication, or may be a remote controller having a simplestructure to make BLE communication.

If the remote control device 100 is realized as a mobile terminal, themobile terminal may include any one of typical mobile phones, such as acellular phone, a personal communication service (PCS) phone, a GSMphone, a CDMA-2000 phone, and a WCDMA phone, a portable multimediaplayer (PMP), a personal digital assistants (PDA), a smart phone, and amobile broadcast system (MBS).

The lighting device 200 includes at least one light emitting device,receives a signal transmitted from the remote control device 100, andoperates according to the received signal.

The lighting device 200 includes a communication unit to makecommunication with the remote control device 100.

The communication unit may employ the BLE standard the same as thecommunication standard used in the remote control device 100.

Hereinafter, the lighting device 200 will be described in more detail.

FIG. 3 is a block diagram showing a lighting system according to thesecond embodiment.

Referring to FIG. 3, the lighting system according to the secondembodiment includes the remote control device 100, the lighting device200, and a wireless access point (AP) 300.

In other words, the lighting system according to the first embodimentemploys the BLE standard to limit the maximum number of clients (e.g.,up to 8 clients). Accordingly, a great amount of lighting devicesinstalled in a large-scale building cannot be efficiently controlled.

Therefore, the lighting system according to the second embodimentemploys the wireless AP 300 interposed between the remote control device100 and the lighting device 200, so that the lighting device 200 can beeffectively controlled.

In other words, when a great amount of lighting devices installed in thelarge building cannot be controlled in the unit of a group or cannot beintegrally controlled due to the limitation in the maximum number ofclients resulting from the BLE standard, the wireless AP 300 is added asdescribed above, so that the mesh network such as a Zigbee network canbe constructed.

In this case, since a Zigbee device cannot be embedded in the mobileterminal such as a smart phone, the wireless lighting system may beconstructed by using a Wi-Fi AP.

The Zigbee technology used in the second embodiment is one ofrepresentative technologies of a short-range wireless networkrepresenting the characteristics of low power consumption, a low price,and the easiness of the use. The Zigbee technology is a standard forupper-layer protocols and applications based on a physical (PHY) layerand a media access control (MAC) layer of the IEEE 802.15.4 standard.The Zigbee technology is the most appropriate communication scheme tothe construction of a system which does not accelerate a data rate at anear distance and represent the low frequency in the use of a network.

The interface unit 130 serves as a passage for all external devicesconnected to the remote control device 100. The interface unit 130receives data or power from the external device to transmit the data orthe power to each internal component of the remote control device 100 ortransmit the internal data of the remote control device 100 to theexternal device. For example, the interface unit 130 may include awired/wireless headset port, an external charger port, a wired/wirelessdata port, a memory card port, a port connecting a device equipped withan identification unit, an audio input/output (I/O) port, a videoinput/output (I/O) port, and an earplug port.

The memory unit 140 may store programs for the operation of the controlunit 170, or may temporarily store input/output data (e.g., a phonebook, a message, a still image, or a moving picture). The memory unit140 may store data related to various vibrations and various soundeffects output when a touch is input onto a touch screen.

The memory 140 may include a storage medium having at least one type ofa flash memory type, a hard disk type, a multimedia card micro type, acard type of a memory (for example, an SD or XD memory), RAM (RandomAccess Memory), SRAM (Static Random Access Memory), ROM (Read-OnlyMemory), EEPROM (Electrically Erasable Programmable Read-Only Memory),PROM (Programmable Read-Only Memory), MRAM (Magnetic RAM), a magneticdisc, and an optical disc.

The remote control device 100 may operate in relation to a web storageperforming the storage function of the memory 140 over the Internet.

The output unit 150 is used to generate visible, audible, or tactileoutputs. The output unit 150 may include a display unit, a sound effectoutput unit, an alarm unit, and a haptic unit.

The power supply unit 160 receives the external power or the internalpower under the control of the control unit 170 to supply the powerrequired for the operation of each component.

The control unit 170 controls the overall operation of the remotecontrol device 100.

In particular, the control unit 170 may perform a control operation sothat the input signal received through the user input unit 120 istransmitted to the lighting device 200 through the wirelesscommunication module 110.

The control unit 170 may perform a pattern recognition process allowinga writing input or a drawing input performed on the touch screen to berecognized as characters and images.

FIG. 5 is a view showing schematically the wireless communication module110 of the remote control device according to the first embodiment.

Hereinafter, the wireless communication module 110 according to thefirst embodiment will be referred to as a Bluetooth transmit unit 110.

Referring to FIG. 5, the Bluetooth transmit unit 110 includes a bandpass filter (BPF) 1111, a switch unit 1121, a radio frequency processingunit 1131, a Bluetooth baseband core (BBC) unit 1141, a micro-processorunit (μPU) 1151, and a phase locked loop (PLL) unit 1161.

The components may be realized in one chip device, and the chip devicemay be mounted on a substrate and molded with the substrate toconstitute the Bluetooth transmit unit 110.

In addition, components such as a memory, a power supply, a voice CODEC,and a headset interface may be further provided on the above components.

The band pass filter 1111 filters only a signal having a Bluetoothfrequency band among singles introduced through an antenna and transmitsthe filtered signal to the switch unit 1121. The switch unit 1121divides transmit and receive signals from each other and transmits thedivided signals to an antenna or the radio frequency processing unit1131.

The radio frequency processing unit 1131 includes receive and transmitstages (the internal components of the radio frequency processing unit1131 are not shown). The receive stage converts an analog RF signal intoan intermediate band signal, and the transmit stage converts theintermediate band signal into an analog RF signal.

The receive stage includes a low noise amplifier (LNA), a receive bandpass filter (Rx BPF), a frequency mixer, an IF filter, and a receivesignal processing module, and the transmit stage includes a poweramplifier module (PAM), a transmit band pass filter (Tx BPF), afrequency mixer, an IF filter, and a transmit signal processing module.

Since the radio frequency processing unit 1131 follows the BLE standard,the radio frequency processing unit 1131 sets 40 communication channelsto construct a wireless network, and controls the transmission and thereception of the Bluetooth communication.

The BBC 1141 is a part to process a physical-layer protocol, andincludes a fast fourier transform (FFT) circuit, an error correctioncircuit, a digital modulator/demodulator, a channel encoding/decoding.The BBC unit 1141 performs coding/decoding with respect to a Bluetoothband signal and signal-processes the Bluetooth band signal as multimediadata. The BBC unit 1141 controls an input/output device such as adisplay unit or a key pad to provide a user interface.

In addition, when modulating/demodulating transmit and receive signals,the BBC unit 1141 detects the intensity of the signals to generate again control signal, and transmits the gain control signal to the LNA orthe PAM of the RF processing unit 1131 to adjust the signal intensity.

The μPU 1151 controls a network link and executes an application toprocess a digital signal.

The PLL unit 1161 provides a frequency source signal to the RF unit 1131by using a secondary loop filter.

FIG. 6 is a block diagram schematically showing a wireless communicationmodule of the remote control device according to the second embodiment.

Hereinafter, the wireless communication module according to the secondembodiment is called a ZigBee transmit module.

The ZigBee transmit module 110 may include a signal processing unit1112, a ZigBee processing unit 1122, and a ZigBee transmit unit 1132.

The signal processing unit 1112 converts the signal input through theuser input unit 120 into a digital signal to be transmitted to theZigBee processing unit 1122.

The ZigBee processing unit 1122 encodes the digital signal, which isreceived through the signal processing unit 1112, through a directsequence spread spectrum (DSSS) scheme and transmits the digital signalto the ZigBee transmit unit 1132. The DSSS scheme is one of a spreadspectrum (SS) scheme. According to the DSSS, digital signals aredistributed with a wide band under low power, and the distributeddigital signals are simultaneously transmitted. Although noise occursduring communication, since the noise is spread when the signal isrecovered, the noise slightly affects the communication. In addition,since the noise does not generate a strong signal, the noise does notinterrupt another communication.

The ZigBee transmit unit 1132 modulates signals encoded by the ZigBeeprocessing unit 1122 according to the IEEE 802.15.4 standard andtransmits the signals to the lighting device 200.

As described above, the remote control device according to theembodiment wirelessly transmits a control signal to the lighting device200 through the BLE standard or the ZigBee standard.

For example, the power supply unit 210 may receive AC power of 110V to220V and supply DC current of one of 25V, 50V, and 100V to the lightingdriving unit 220. In addition, the power supply unit 210 may supply theDC power of 3V to the wireless communication module 240 by using theinput AC power.

The lighting driving unit 220 receives power from the power supply unit210 and changes driving power to be supplied to the lighting unit 230based on the received power.

The lighting unit 230 may include at least one light emitting device,and a plurality of light emitting devices may be divided into aplurality of groups. The light emitting device may be a lightingemitting diode chip to emit one of red, green, and blue lights.

The lighting emitting diode chip may include a lateral type lightemitting diode chip or a vertical type light emitting diode chip. Thelight emitting diode may emit one of blue, red, yellow, and greenlights.

The wireless communication module 240 makes wireless communication withthe remote control device 100.

The wireless communication module 240 receives the control signaltransmitted from the remote control device 100 and transmits the controlsignal to the lighting driving unit 220, so that the power supplied tothe lighting unit 230 may be controlled.

In this case, the wireless communication module 240 may have componentscorresponding to the components constituting the Bluetooth transmitmodule or the ZigBee transmit module of the remote control device 100.

The lighting device 200 is provided therein with the wirelesscommunication module 240 to receive the control signal from the remotecontrol device 100 through the wireless communication module 240, and tocontrol the lighting unit 230 based on the control signal.

Hereinafter, the structure of the lighting device 200 will be describedin more detail.

In the following description, the lighting device is assigned withreference numeral 400. However, the lighting device 400 has the samecomponents as those of the lighting device 200, and a differentreference numeral is assigned with the lighting device for theconvenience of explanation.

FIG. 8 is a view showing the structure of the lighting device accordingto the embodiment.

Referring to FIG. 8, the lighting device 400 includes a heat radiationframe 410, a heat radiation plate 420, a light emitting device 430, adiffusion frame 440, a support frame 450, and a module 460.

The heat radiation frame 410 includes an upper end portion having a flattop surface and a lower end portion substantially vertically extendingalong the outer peripheral surface of the flat surface of the upper endportion.

The heat radiation frame 410 may include a metallic material or a resinmaterial representing superior heat radiation efficiency, but theembodiment is not limited thereto. For example, the material of the heatradiation frame 410 may include at least one of aluminum (Al), nickel(Ni), copper (Cu), silver (Ag), tin (Sn), and magnesium (Mg).

The heat radiation plate 420 may be provided on the top surface of theheat radiation frame 410. The heat radiation plate 420 may include athermal conductive silicon pad or a thermal conductive tape representingsuperior thermal conductivity. The heat radiation plate 420 mayeffectively transfer heat generate from the light emitting device 430provided on the top surface thereof to the heat radiation frame 410.

The light emitting device 430 is formed on the heat radiation plate 420.In particular, the light emitting device 430 includes at least one lightemitting diode, and the light emitting diode may be secured on asubstrate.

The substrate has a rectangular shape, but the embodiment is not limitedthereto. The substrate may be provided by printing a circuit pattern onan insulator. For example, the typical printed circuit board (PCB) mayinclude a metal core PCB, a flexible PCB, and a ceramic PCB. Inaddition, the substrate may have a COB (chips on board) type in whichLED chips, which are not packaged, are directly bonded on the PCB.

In addition, the substrate may include a material to effectively reflectlight, or the surface of the substrate may have a color such as a goldcolor or a silver color to effectively reflect the light.

At least one light emitting device 430 is provided on the substrate, andmay include a light emitting diode chip to emit red, green, and bluelights or a light emitting diode chip to emit UV.

The light emitting diode may have the lateral type or the vertical type.The light emitting diode may emit one of blue, red, yellow, and greenlights.

Although not shown in drawings, a lens may be additionally formed on thelight emitting device 430. The lens may be provided on the substrate tocover the light emitting device 430. The lens adjusts the orientationangle or the direction of the light emitted from the light emittingdevice 430. In this case, the lens is a semispherical type lens, and maybe fully filled with transmissive resin such as silicon resin or epoxyresin without the empty space. The transmissive resin may includephosphors that are entirely distributed throughout the transmissiveresin or distributed in a portion of the transmissive resin.

When the light emitting device 430 is a blue light emitting diode, thephosphors contained in the transmissive resin of the lens may include atleast one of garnet-based phosphors (YAG, or TAG), silicate-basedphosphors, nitride-based phosphors, and oxynitride-based phosphors.

Only the yellow-based phosphors may be contained in the transmissiveresin in order to realize natural light (white light). However, in orderto improve the color rendering index and reduce a color temperature, thetransmissive resin may further include green-based phosphors orred-based phosphors.

When various types of phosphors are mixed and contained in thetransmissive resin, the contents of the phosphors may vary according thecolors of the phosphors. In other words, green-based phosphors may beused with the content higher than that of the red-based phosphors, andyellow-based phosphors may be used with the content higher than that ofthe green-based phosphors.

The yellow-based phosphors include YAG of the garnet-based phosphors andsilicate-based phosphors, the green-based phosphors includesilicate-based phosphors and oxynitride-based phosphors, and thered-based phosphors include nitride-based phosphors.

The transmissive resin may include the mixture of various phosphors, andmay include a red-based phosphor layer, a green-based phosphor layer,and a yellow-based phosphor layer which are separately formed from eachother.

The diffusion frame 440 is provided on the heat radiation frame 410 andthe heat radiation plate 420 to cover the light emitting device 430.

The diffusion frame 440 has a bulb shape, and the inner surface of thediffusion frame 440 is coated with ivory white pigments. The ivory whitepigments may contain a diffusion agent to diffuse the light passingthrough the heat radiation frame 410 into the inner surface of thediffusion frame 440.

Although the material of the diffusion frame 440 include glass, sincethe glass is weak against the load or the external shock, the glass maypreferably include plastic, polypropylene (PP), and polyethylene (PE).More preferably, the material constituting the heat radiation frame 410may include diffusion polycarbonate (PC) representing superior lightresistance, heat resistance, and impact strength.

The inner surface of the diffusion frame 440 may be provided with thesurface roughness greater than the surface roughness of the outersurface of the diffusion frame 440. In other words, when the lightgenerated from the light emitting device 430 is irradiated onto theinner surface of the diffusion frame 440 and discharged to the outside,the light irradiated onto the inner surface of the diffusion frame 440may be discharged to the outside after the light is sufficientlyscattered and diffused. If the inner surface roughness and the outersurface roughness of the diffusion frame 440 are formed with the abovecharacteristic, the light emitting characteristic can be improved.

In addition, the diffusion frame 440 is preferably formed through a blowmolding scheme to widen the orientation angle of light.

The support frame 450 may include a material representing superiorinsulating property and superior endurance. For example, the supportframe 450 may include a resin material.

The support frame 450 has a receiving space to receive the module 460therein.

The support frame 450 prevents the short phenomenon between the heatradiation frame 410 and the module 460 to improve the withstand voltageof the lighting device 400.

A socket is formed at a lower portion of the support frame 450. Thesocket is electrically connected to an external power supply so that theexternal power is supplied to the module 460 received in the supportframe 450.

FIG. 9 is a view used to explain the module 460 shown in FIG. 8.

Referring to FIG. 9, the module 460 includes a power supply module 462and a wireless communication module 464. The power supply module 462 isphysically separated from the wireless communication module 464.

The power supply module 462 and the wireless communication module 464may be vertically erected in the receiving space of the support frame450. When the power supply module 462 and the wireless communicationmodule 464 are vertically provided, the air flow vertically occurs dueto the convection phenomenon inside the support frame 450, which is lessrepresented in the horizontal-direction arrangement, so that the heatradiation efficiency of the lighting device 400 can be increased.

In this case, the power supply module 462 is connected to a wire havinga positive terminal and a negative terminal, and the wire iselectrically connected to the light emitting device 430 provided on theheat radiation plate 420.

FIGS. 10 and 11 are views showing the structure of an antenna accordingto the first embodiment.

According to the embodiment, since the wireless communication module 464is provided in the lighting device 400, the antenna 470 used to transmitand receive signals by the wireless communication module 464 isrequired.

Referring to FIGS. 10 and 11, the antenna 470 according to theembodiment is provided on the heat radiation plate 420.

In this case, when the antenna 470 is provided inside the heat radiationframe 410 or the support frame 450, the signals cannot be normallyreceived or transmitted due to the electromagnetic wave shielding.Therefore, according to the embodiment, the antenna is provided on theheat radiation plate 420, so that the antenna 470 can be exposed to theoutside the heat radiation frame 410 or the support frame 450.

The antenna 470 is spaced apart from the light emitting device 430provided on the heat radiation plate 420 by a predetermined distance.Accordingly, the light of the light emitting device 430 can be preventedfrom being diffused due to the antenna 470, and the performance ofreceiving the signal of the antenna 470 can be prevented from beingdegraded due to the light emitting device 430.

Therefore, the antenna 470 makes contact with the heat radiation plate420, and includes a first pattern 471 formed perpendicularly to the heatradiation plate 420 and a second pattern 472 formed perpendicularly tothe heat radiation plate 420 while extending from the first pattern 471.
